Let's divide 1122091 by 645
Our goal is to divide 1122091 by 645.

Going ahead to step 1:
645 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 645

On to step 2:
The number 645 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 645

Going ahead to step 3:
The number 645 fits into 112 0 times, leaving a remainder of 112.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 112 to get 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 645

Step 4:
When dividing 1122 by 645, we get 1 with a remainder of 477.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 645 from 1122 leaves us with 477.
Take the next digit (0) from the dividend and append it to 477, then repeat: 4770 / 645

Advancing to step 5:
If we divide 4770 by 645, we get 7 and a remainder of 255.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 4515 from 4770 and we're left with 255.
Bring next digit (9) of the dividend behind the 255 and repeat the process: 2559 / 645

Let's proceed to step 6:
If we divide 2559 by 645, we get 3 and a remainder of 624.
Put 3 as the next digit of the answer. 
Result so far: 173.0
The remainder is 624 after subtracting 1935 from 2559.
Bring next digit (1) of the dividend behind the 624 and repeat the process: 6241 / 645

On to step 7:
The number 645 fits into 6241 9 times, leaving a remainder of 436.
The number 9 becomes the next digit in our result. 
Result so far: 1739.0
Subtracting 5805 from 6241 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 8:
4360 divided by 645 is 6 with a remainder of 490.
The next digit of our result is 6. 
Result so far: 1739.6
If we take 3870 away from 4360, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 9:
If we divide 4900 by 645, we get 7 and a remainder of 385.
Record the quotient 7 as the next digit in the result. 
Result so far: 1739.67
If we subtract 4515 from 4900, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 10:
3850 divided by 645 is 5 with a remainder of 625.
The next digit of our result is 5. 
Result so far: 1739.675
Deduct 3225 from 3850 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Step 11:
The number 645 fits into 6250 9 times, leaving a remainder of 445.
Put 9 as the next digit of the answer. 
Result so far: 1739.6759
If we take 5805 away from 6250, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 12:
645 goes into 4450 6 times with a remainder of 580.
Put 6 as the next digit of the answer. 
Result so far: 1739.67596
Deduct 3870 from 4450 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 13:
645 can be fit into 5800 8 times, resulting in a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 1739.675968
Subtracting 5160 from 5800 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
645 goes into 6400 9 times with a remainder of 595.
Write down 9 as next digit of the result. 
Result so far: 1739.6759689
Deduct 5805 from 6400 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 15:
If we divide 5950 by 645, we get 9 and a remainder of 145.
The number 9 becomes the next digit in our result. 
Result so far: 1739.67596899
Deduct 5805 from 5950 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

In conclusion, the division gives 1739.67596899 with a balance of 1.45e-07.
